Hazelcast offers a specification-compliant JCache implementation. The Hazelcast JCache implementation is 100% TCK (Technology Compatibility Kit) compliant and therefore passes all specification requirements. You can create and configure JCache using the Cache custom resource.

Configuring a Cache Resource

Example Configuration

The following Cache custom resource creates a cache configuration for the Hazelcast custom resource that is defined in the hazelcastResourceName field.

Example configuration
